IPC: F16L3/00
Filed: 1978-02-10
Abstract: PURPOSE: To eliminate the need for preparing many kinds of ducts, to reduce the nymbe of wiring steps, and to provide interchangeability of ducts by making the height of ducts variable according to the set height of cinder concrete.  
     CONSTITUTION: With the hight H of cinder concrete 6 (to be cast by construction contractor) determined, screws 18 are untightened and a duct body 5 is slid up and down so that it will be flush with the cinder concrete 6; after confirmation of dimensions, the screws 18 are tightened to fix support metals 17 and duct side plates 8. The support metals 17 are fixed to an unfinished floor 7 with anchor bolts 19. Then the cinder concrete 6 is cast by the construction contractor up to the determined hight H. As a result, the duct 5 is efficiently fixed to the unfinished floor 7 and the duct cover 15 is flush with the cinder concrete 6. This constitution eliminates the need for site-by-site fabrication of wiring ducts, improving working efficiency.

Similarly, through control of rotation of a regulating handle 48, a relative rotation phase between the reduction drum 15 and an upper cogging drum 16 is regulated. Further, a handle is provided for regulating a relative rotation phase between the reduction drum 15 and a lower cogging 17. Since regulation control is practicable during operation of the folding device without stopping the folding device, working efficiency is prevented from lowering.

Abstract: PURPOSE:To improve the response and the stable operation of a feedback loop by providing a low pass filter, a DC component detection means and a feedback signal generator to the frequency feedback type direct receiver. CONSTITUTION:A DC component included in a detection signal from a signal processing section 3 of the frequency feedback type direct receiver is fed back to deviate a tuning voltage of a local oscillator 2 thereby eliminating the DC component.

Title: Cooperating type pulse combustion device
Inventor: SAITO KAZUO
IPC: F23C15/00
Filed: 1988-01-26
Abstract: PURPOSE:To increase a variable width of a thermal input and enable a stable pulse combustion to be carried out by a method wherein a mixing variable device capable of varying a mixing speed of fuel and air is arranged at a downstream side of a flow rate control valve within an air supplying passage and then the mixing variable device is controlled in cooperation with a degree of opening of the fuel flow rate adjusting valve. CONSTITUTION:Swirling devices 11a and 11b are arranged in downstream sides of flow rate controlling valves 5a and 5b within each of air supplying passages 3a and 3b connected to each of combustion chambers 2a and 2b. When the fuel flow rate is low, an angle of a vane 13 of each of the swirling devices 11a and 11b is set to a small angle in respect to a flowing direction under a controlling action of control devices 16a and 16b for inputting a degree of opening signal of a fuel flow rate adjusting valve 17. In turn, when a fuel flow rate is high, the angle of the vane is set to a larger angle. When the angle of the vane 13 is high, a mixing speed of fuel and air is increased and in turn when the angle is low, the mixing speed is decreased. As a result, it is possible to cause a phase between a heat generating speed and a pressure variation to be always approached to the same phase and then secure a vibrating energy required for continuation of a pulse combustion. Accordingly, it is possible to get an enlargement of a variable width of capability and a realization of the pulse combustion.
